HISTORY…

1863 1886 1910

Sergei Vasilyevich Lebedev

In 1929, Eduard Tschunker and Walter Bock, working for

IG Farben in Germany, made a copolymer of styrene and

butadiene that could be used in automobile tires.

ENT



HazaqdIdentification

N-butane (feedstock)

• colourless gas, with boiling point -0.5°C

• Highly flammable

• Contact with liquid can cause frostbite.

Butadiene (Product)

• Boiling point -4.4°C

• Extremely reactive with oxidizing material

• Carcinogenic

• Skin contact can cause frostbite.

WASTE TREATMENT

STEAM STRIPPING PROCESS :

• Separate water and organic substances troughdistillation process.

• Water become heavy product and volatile organicas a light

• Used since only small concentration of organic inthe feed.

• Temperature as a main function.

What happensto butadiene

when it entersenvironment?

Breaks downquickly in

sunlight anddegrades in theair with a half-life of less than

two hours

Moderatelytoxic to aquatic

organisms.

Has a lowpotential to

bioaccumulate

Biodegradation

is not likely tocontribute

significantly toremoval of

butadiene fromthe soil

High volatility

& low-watersolubility
